American artist and sculptor Daniel Arsham has teamed up with musician, fashion designer and producer Pharrell Williams to create a series of sculptural keyboards that resemble fossils more than they do musical instruments.

The fossilized re-creations are based off the design of the 1980s Casio MT-500 keyboard and drumkit, the very first instrument Pharrell ever made music on. Arsham modelled the keyboards using a mix of geological materials such as volcanic ash, crystal, and steel, resulting in their archaic experience.

Unveiled at an exhibition and event hosted at Standard East Village in New York on September 11th, 2013, the instruments are unlike any others. The celebration also included a tactile, interactive experience, where guests could handle the objects with white gloves – as if handling a delicate relic from the past.
